对神光Ⅱ条件下辐射驱动内爆的不对称性进行了二维数值模拟。模拟结果表明，靶丸内爆的不对称性对辐射温度源的不均匀性非常敏感，ＤＴ平均压缩度则对其不敏感。同时，内爆不对称性对中子产额和内爆效率有一定的影响。辐射驱动内爆的不对称性可以利用辐射温度源的时间调制得到明显的改善。
Two-dimensional numerical simulation of the asymmetry of radiation-driven implosion under SGⅡ was carried out. The simulation results show that the asymmetry of the implosion of the target is very sensitive to the inhomogeneity of the radiation temperature source and the DT average compressibility is not sensitive to it. At the same time, the implosion asymmetry has a certain impact on the neutron yield and implosion efficiency. Asymmetry of radiation-driven implosion can be significantly improved with time modulation of the radiation temperature source.
